TECHNICAL FIELD

The following discussion generally relates to power management inwireless communications systems. More particularly, the followingdiscussion relates to systems, devices, and automated processes thatreduce power drawn by radio frequency (RF) radios based on commercialpower interrupts or failures in 5G data networks or the like by smartbandwidth adaptation and traffic loading increasing the operating timeof the switched backup uninterruptible power supply (UPS).

BACKGROUND

The 5G data standard and telephone networks were developed to providegreatly improved bandwidth and quality of service to mobile telephones,computers, internet-of-things (IoT) devices, and the like. Thehigh-bandwidth 5G networks, however, face additional challenges that arenow being recognized. In part, because of the high-bandwidth, the 5Gbase station is expected to consume roughly three times as much power asthe legacy 4G base stations in use. Further, more 5G base stations areneeded to cover the same area as the legacy 4G base stations. Hence, notonly does each 5G base consume three times the power of the 4G basestation, for coverage of the same area more 5G base stations are in use,and as a result, significant increases in power consumption will result.

Further, along with the increases in power usage, in the case of ACpower outages, the 5G base stations are required to have a batterybackup to ensure service offerings during AC power outages. Thesebattery backup units are expensive, and the cost for the battery backupis in part determined by the amount of the power needed and subsequentlyconsumed by the RF radio transmitters and receivers at the 5G basestation; which in this case exceeds the legacy 4G base stations by bothnumber in use and the power need for each 5G base station. In thesecases in which significant amounts of power are needed and consumed bycertain 5G base stations, there is needed several serially or parallellyconnected backup power packs that result in multiple fold cost increasesin the eventual configured 5G base stations for each cell site.

The use of beam management is defined as the process of acquiring andmaintaining a set of beams, which are originated at the gNB and/or theUE, and it is desirable to implement beam management to reduce powerneeds for the downlink and uplink transmission and reception.

It is desired to provide solutions to implement choking of heavilyloaded channels as apposed to bandwidth reductions. It is desired toreduce power consumption at a cell site can be reduced by cutting offheavily loaded channels (i.e., limiting users); the power consumptionsaving can be shown in a functional relationship. That is, rather thanapply traffic management to guarantee fairness amongst users, andtraffic management solutions may be implemented that will take intoaccount additional consideration amongst users to reduce powerconsumption incrementally for individual channels that can extend backupbattery life with less power consumption.

It is, therefore, desirable to create systems, devices, and automatedprocesses that can monitor commercial power interrupts and failures andallow different configurations of base station components to operate inthe desired cell network. It is also desirable to improve connectivityand to the operating time for base station equipment operating in backuppower modes using backup batteries at cell sites within 5G or similarnetworks.

Furthermore, other desirable features and characteristics of the presentinvention will become apparent from the subsequent detailed descriptionand the appended claims, taken in conjunction with the accompanyingdrawings and the foregoing technical field and background.

DETAILED DESCRIPTION

The following detailed description is intended to provide severalexamples that will illustrate the broader concepts that are set forthherein, but it is not intended to limit the invention or the applicationand uses of the invention. Furthermore, there is no intention to bebound by any theory presented in the preceding background or thefollowing detailed description.

When connecting a 5G base station to the power grid, this does notalways guarantee that power is available and provided to the 5G basecontinuously all the time without interruption because of a plethora ofenvironmental and operating reasons such as accidents, lightningstrikes, rolling blackouts, etc. Therefore, for a robust and reliable 5Gservice made available from a 5G base station, carriers have to build ina backup power system. It is the norm to provide backup power to themacrocells in a 5G network, and often the macro level has sufficientservice. However, the power-consuming small cell structure requiresadded power backup that is not usually available in legacy 4G cell towerpower deployments. Hence, added backup power is essential to enable theproper functioning of the small cell rollout.

In 5G networks, the RF radio units are required to have a battery backupto ensure service offerings during an AC power outage. The batterybackup units are expensive, and the cost for each battery backup iscalculated by the power consumed by the radio unit, the backup duration,and how many operating carriers are at a base station or network.

Currently, there are a number of obstacles or drawbacks that preventoptimization of battery backup capacity when a power interrupt or outageoccurs. It is a desire that the required battery backup capacity can beoptimized as follows:

(1) Shut down Operating carriers: this is not a preferred option, asthis impacts the user experience, lack of emergency calls, such as E911,resulting in users canceling their service and switching to operatorswho have battery backup services; (2) Reduce the operating carrierBandwidth: this is not easily feasible in current operations as changingthe operating carrier BW requires a new cell configuration on the sameradio with lower channel BW, and (3) this will also cause serviceinterruption as changing the operating BW will cause the site to restartfor the new channel BW to be in effect.

The advanced capabilities of 5G small cells mean added powerrequirements. Increased data traffic requires more computational power.Although massive MIMO can help improve spectral efficiency, powerefficiency is generally lower, and a typical three-sector small cell canrequire 200-1,000 watts of power.

There is a need to receive power by a large number of small cells in acost-effective and repeatable way that supports fast and efficientrollouts. The first step involves recognizing that the traditional modelfor powering macro cell sites does not apply to small cells.

The A-frame has a duration of 10 ms, which consists of 10 subframeshaving 1 ms duration each similar to LTE technology. Each subframe canhave 2μ slots. Each slot consists of 14 Orthogonal frequency-divisionmultiplexings (OFDM) symbols. The radio frame of 10 ms is transmittedcontinuously as per TDD topology one after the other. The subframe is offixed duration (i.e., 1 ms), whereas slot length varies based onsubcarrier spacing and number of slots per subframe. Each slot occupieseither 14 OFDM symbols or 12 OFDM symbols based on normal Cyclic Prefix(CP) and extended CP, respectively.

The scheduler can be configured to reduce enabled slots (i.e., uplink ordownlink), for example, implementing mini-slots that do not require all14 symbols in a slot configuration for scheduling to manage powerconsumption without causing any cell site interruptions in service.Also, it is desirable to change the frequency in a time domain forscheduling as well the enabled/not enabled slots. The scheduler canimplement scheduling based on the time domain, and the mini-slots areenabled or disabled to reduce the power requirements of all theoperating carriers of cell sites in a network, particularly in case ofan AC power outage or interruption for enhanced power managementefficiencies of each cell site.

The channel control by a control unit can be defined as the MediumAccess Control (MAC) Layer of NR that provides services to the RadioLink Control (RLC) Layer in the form of logical channels. A logicalchannel is defined by the type of information carried and is a controlchannel when used for transmission of control and configurationinformation or is a traffic channel when used for the user data.

The channel control is configured into radio resources that are composedof two domains frequency and time. In the frequency domain, the channelbandwidth ranges from 1 to 20 MHz. The total available bandwidth whichincludes 1.4, 3, 5, 10, 15 and 20 MHz is divided into sub-channels of 12sub-carriers of 15 KHz, totaling 180 KHz. The minimum allocation unit ofradio resources is called Resource Block (RB). A single RB consists of180 KHz in the frequency domain and 1 ms in the time domain. In the timedomain, radio resources are divided into Transmission Time Intervals(TTI), also called sub-frame, with duration of 1 ms. One frame is formedby 10 TTI. Each TTI consists of two 0.5 ms slots, and each slot includesseven symbols. A LTE-A network within the 5G environment (i.e 5G LTE-A).

The mini-slot is a minimum scheduling unit used in 5G NR. It occupies 2,4, or 7 OFDM symbols (regardless of numerology), so a user can beallocated a mini-slot, which is less than the slot (14 symbols), and itis suitable for low latency communication. It enables what is callednon-slot based scheduling that will have higher priority than normalEnhanced Mobile Broadband (eMBB) user, so it can preempt other eMBBtransmissions as it has requirements for lower latency.

The slot can be classified as downlink (all symbols are dedicated fordownlink) or uplink (all symbols are dedicated for uplink) or mixeduplink and downlink transmissions. In the case of Frequency DivisionDuplex (FDD), all symbols within a slot for a downlink carrier are usedfor downlink transmissions and all symbols within a slot for an uplinkcarrier are used for uplink transmissions. New Radio (NR) Time DivisionDuplex (TDD) uses a flexible slot configuration. The OFDM symbols in aslot can be classified as ‘downlink,’ ‘flexible,’ or ‘uplink.’ Flexiblesymbols can be configured either for uplink or for downlinktransmissions. NR TDD uses a flexible slot configuration. OFDM symbolsin a slot can be classified as ‘downlink’, ‘flexible’, or ‘uplink’. Theflexible symbol can be configured either for uplink or for downlinktransmissions. In FDD mode, both uplink and downlink can transmit at thesame time at different spectrum frequencies. In TDD mode, both uplinkand downlink use the same spectrum frequencies but at different times.

The MIMO antennas communicate with multiple users using focused beams ofradio waves (“beamforming”). This increases channel efficiency alongwith data transfer rates and reduces the possibility of interference.Also, particular MIMO antenna configurations can be implemented to focusradio energy directly towards the connected device and can identify theexact amount of power and energy required to further reduce energyconsumption for both the base station and the user equipment (UE).

Traffic shaping can reduce power consumption at a cell site (i.e., Basestation). For example, Traffic shaping rules can be implemented to allowreal-time voice and video and to block or throttle applications such aspeer to peer applications, and social networks. When channels are notcongested, the power consumption is reduced because of the low trafficrate. The same is not true for the case of high traffic load as thepower consumption is not be reduced because, during high traffic loads,there are no empty subframes left. The user, when engaging in channelselection, can be moved to different channels. For example, users can bemoved from a channel at 20 Mhz to a 40 Mhz channel or to another.

In 5G NR, beams based cell sector coverage is used, which increases thelink budget and overcomes the disadvantages of the mm-wave channel. Inother words, all the data transmissions and key signaling transmissionsare beam-formed (directional).

The RF radios and antennas use a fixed input power that is based on fullload RF conditions. When commercial power is interrupted, lost, ordramatically reduced, the RF radio is not able to receive notice tomodulate its power consumption accordingly. In other words, the RF isnot informed, nor is the RF radio configured to be advised of acommercial power loss and can change or drop its preconfigured inputpower requirements. The inability to change the input power requirementsof the RF radio results in lower performance in its operation by causinga faster drain on its battery backup systems.

The 5G New Radio (NR) is the global standard for a unified, capable 5Gwireless interface, can deliver a faster broadband experience, and isdesigned to have an initial bandwidth part (BWP) that is used by all theUE during initial access and dedicated BWP for a UE or group of UEs thatwill apply for data allocations. The BWP adaptation is controlled by agNB node (radio access network (RAN)+distributed unit (DU)/centralizedunit (CU) for 5G). There can be multiple smaller BWP(s) that will bepredefined by the operator to be used during AC power outages (i.e., aRAN slicing architecture that has multiple sets of functional splits andfunction placement in one cell). In an exemplary embodiment, anotheroption is to use a gradual reduction in the operating BWP. For (e.g., tostart with only a 25% percent reduction in BW and then gradually move tolower numbers if the power is not restored). With this process, the userexperience can avoid degradation in the case of short AC power outages.The network slicing can also be linked to the BWP, during an AC poweroutage or light network load operations, the minimization of the powerconsumption gNB can be done by control of the slice and BWP mutualassociation. For example, the operator can choose to merge all theavailable slices into the smaller BWP. The operator can choose to definethe BWP and slice mapping during an AC power outage when there aremultiple BWP defined that are made available during AC power outages

It is desirable to achieve cost savings using intelligent solutions toreduce the power consumption of 5G base stations when operating in abackup power mode while meeting sufficient regulatory operatingrequirements to prevent a shut-down of the radio transmitter.

It is desirable to limit the number of backup power supplies that areneeded for use when operating the 5G base station in a backup power modefor component cost savings, current usage, and efficiency.

It is desirable to provide systems and methods for operating adaptivemini-slot management to monitor power and channel traffic at a pluralityof cell sites in the network; to enable and disable a set of mini-slotsin a downlink (DL) pattern and an uplink (UL) pattern including at leasttwo concatenated patterns jointly repeated with periodicity in a slotconfiguration period for new radio (NR) communications by users at cellsites in the network; and in response to a request by a user, to reservea number of mini-slots for use in each slot configuration period whereina reserved slot number is responsive to at least one of a condition ofan AC power outage, and reduced channel traffic based on data receivedby the DU/CU about the condition.

It is desirable to provide systems and methods initialize a set ofmini-slots for use when scheduling the UE with by mini-slot assignmentsto dynamically inform the UE about a UL transmit and DL receive patternsfor each mini-slot configuration period wherein an initial set ofmini-slots are enabled in response to data received about a loss ofpower and to reduce channel traffic at mini-slots from the DU/CUmonitoring cell sites of the network. Also, it is desirable to implementa time-domain based schedule to reduce power consumption in the UL andDL transmissions by reductions in slot time via changing a frequency ofthe mini-slot configuration period by applying a set of time-domainscheduling periods for a select number of mini-slots to be enabled ineach time-domain scheduling period.

It is desirable to provide systems and method for operating managementof base stations components that enable the smart management of powerconsumption by implementing adaptable bandwidth control and sliceoffering at cell sites (i.e., nodes) or enabling automated systems toreconfigure component based on examination of the current trafficloading on the antenna to change the mode of operation of the RF radiotransmitter based on evaluating if a degraded RF radio service can beimplemented under the current conditions. If it is possible, the RF EMSor orchestration system will execute a workflow to drop the input powerrequirements on the RF radio. This can reduce the current power drawthat can result in increases in the amount of time the RFradios/antennas can operate in a backup UPS power mode and provideservice.

It is desirable to implement processes where the operator can choose toclose some slice offerings and continue only higher priority slice(s).The Radio AC power outage detection by DU/CU, DU/CU, or NFMF can alsodetect AC power outage via FCAPs and activate the solution. During an ACpower outage, the RAN will notify to the control unit (DU: DistributedUnit or CU: Central Unit). The DU/CU will initiate moving of all usertraffic to the designated lower BWP(s) (e.g., initial BWP) whileshutting down all the other BWP in the current operating carrier. Basedon the configuration, the DU/CU will move all the users and/or slices tothe smaller BWP(s) during an AC power outage or during light networkload to minimize power consumption gNB and will notify the users of thechange in the assigned BWP. The Users will stop monitoring the currentBWP and will immediately start following only the lower BWP.

In a multi-carrier operation, the DU/CU can also move all the traffic toa single carrier based on BWP or slice prioritization configurations.After full power restores or loading on the RAN has increased, gNB canre-activate all the dedicated BWP or slices and move the usersseamlessly to their respective BWP or slice(s). The reduced bandwidthassignment to UE in Multi-User MIMO (MU-MIMO) operation. If the RANScheduler is operating in MU-MIMO operation and decides that all servingusers can be assigned to the same lower PRBs, DU/CU can turn offtransmission on other sub-carriers thereby resulting in power saving.The lower PRBs assignment for MU-MIMO can be prioritized based on BWPand/or Slicing predefined priorities.

It is desirable to change required levels on the input power setting ofthe RF radio in response to feedback messages of detected inputcommercial power level changes or interrupts by the RF radio to reducethe operating RF radio power consumption. The RF radio operating powersetting is reduced based on the immediate operational requirements,including determinations of the available RF service on theantenna/radio to provide for a prolonged operating time of airtime ofthe antenna reception and RF radio transmitter.

It is desirable to enable automated systems to reconfigure componentsbased on examination of the current traffic loading on the antenna tochange the mode of operation of the RF radio transmitter based onevaluating if a degraded RF radio service can be implemented under thecurrent conditions. If it is possible, the RF EMS or orchestrationsystem will execute a workflow to drop the input power requirements onthe RF radio. This can reduce the current power draw that can result inincreases in the amount of time the RF radios/antennas can operate in abackup UPS power mode and provide service.

It is desirable to provide systems and methods that when the RF radio ofthe operating cell (i.e., gNB node) incurs a drop or interrupt ofcommercial power at the input to the base station the operationalsystems are altered to compensate for the loss of commercial power to areduce RF radio current draw.

Wireless mobile communication technology uses various standards andprotocols to transmit data between a base transceiver station (BTS) anda wireless mobile device. The deployment of a large number of smallcells presents a need for energy efficiency power management solutionsin fifth-generation (5G) cellular networks. While massive multiple-inputmultiple outputs (MIMO) will reduce the transmission power, it resultsin not only computational cost, but for the computation required, theinput power requirements for transmission can be a significant factorfor power energy efficiency (especially when operating in a backup mode)of 5G small cell networks. In 3GPP radio access networks (RANs) in LTEsystems, the BTS can be a combination of evolved Node Bs (also commonlydenoted as enhanced Node Bs, eNodeBs, or eNBs) and Radio NetworkControllers (RNCs) in a Universal Terrestrial Radio Access Network(UTRAN), which communicates with the wireless mobile device, known asuser equipment (UE). A downlink (DL) transmission can be a communicationfrom the BTS (or eNodeB) to the wireless mobile device (or UE), and anuplink (UL) transmission can be a communication from the wireless mobiledevice to the BTS.

The power consumption of base stations (BSs) is classified into threetypes, which are the transmission power, the computational power, andpower for base station operation. The transmission power is the powerused by the power amplifiers (PAs) and RF chains, which perform thewireless signals change, i.e., signal transforming between the basebandsignals and the wireless radio signals. The computation power representsthe energy consumed at baseband units (BBU's), which includes digitalsingle processing functions, management, and control functions for BSsand the communication functions among the core network and BSs. Allthese operations are executed by software and realized at semiconductorchips. The additional power represents the power consumed formaintaining the operation of BSs. More specifically, the additionalpower includes the power lost at the exchange from the power grid to themain supply, at the exchange between different direct current to directcurrent (DC-DC) power supply, and the power consumed for active coolingat BSs.

Power loss and outages are commonplace in networks today as a result ofnatural disasters, rolling brownouts, etc. Base stations include backuppower (e.g., batteries), these forms of backup power may not providesufficient power during lengthy AC power outages, the use of commercialwireless communications services may increase due to users' needs and/ordesires.

The physical or network node either represents an access node (e.g.,Radio Distributed Units) or non-access node (e.g., servers and routers),while a physical link represents an optical fiber link between twophysical nodes. Every physical node is characterized by a set ofavailable resources, namely computation (CPU), memory (RAM), andstorage, which define the load characteristics of a cell site. Eachphysical link is characterized by a bandwidth capacity and a latencyvalue, which is the time needed by a flow to traverse that link.Finally, both physical nodes and links have associated utilization powerrequirements for each type of available resource.

The power delivery to a BS is rectified and regulated to a nominalmeasured DC voltage 48 (i.e., voltage direct current (VDC)), which isfed to a backup battery or a set of backup batteries for charging. Therectifier unit includes circuitry to keep the batteries fully chargedand ready in case of a commercial power interrupt or failure. At fullcharge, the backup battery is kept at a voltage in the vicinity of 50volts. Also, the vendors/operators may opt for a DC voltage of −24V orother DC voltage setting and not the typical 48V setting. The batterypack parameter in general per customer's requirement is in the order of2-hour work time or other operator backup time settings (e.g., theoperators may choose a 2-hour battery backup, 4-hour or 8-hour . . . asdesired or required for operations) under 100 W (in this case, the poweris calculated per RU power consumption and is a variable quantity . . .) AC system, 48.1V/65 Ah battery that can last for about 150 minuteswith a full load.

Base stations typically use a 48V input supply that is stepped down byDC/DC converters to 24V or 12V, which can be reduced to meet the DCvoltage level of each module.

In the 3GPP specification, the receive and transmit bandwidth of a UEcan be adjusted to a subset of total cell bandwidth referred to as BWP.The bandwidth can be configured to shrink during a period of lowactivity for power reduction, and also the bandwidth location can bechanged to allow different services. In an exemplary embodiment, thebandwidth adaption can be achieved by configuring the UE with BWP(s)informed to the UE of which of the configured BWPs is currently activeone.

The commercial power interface 150 may receive power AC power from apublic utility or other sources. The antenna 133 and antenna interface132 control the signal to the UEs 110. The radio network controller 142can control the RF transmit output via the RF radio 135 to conservepower usage to reduce the power draw on the USP 156. By reducing thecommunication bit rate, the RF power can be reduced in decibels (“dB”).Additionally, step reductions can be implemented. The battery circuit154 can be configured as a rectifier type switch that can switch theoutput power from the UPS 156 at multiple levels. The Base Stationcontroller 138 can include power control features to control the powerdrawn by the base station 138. Additionally, the base station controller138 can communicate wirelessly with a power management system 170 thatcan confirm the AC power outage or interrupt on the front end to changethe power input power levels of multiple small cells 121, 122, and 123,and a number of UEs 110 connected to the Node 140 and resources in aslice of a node (gNB).

In an exemplary embodiment, UEs 110 can be configured with a maximum of4 BWP for Downlink and Uplink, but at a given point of time, only oneBWP is active for downlink and one for uplink. The BWPs can beconfigured to enable each of the UEs 110 to operate in a narrowbandwidth, and when the user demands more data (bursty traffic), it caninform gNB to enable full bandwidth. When gNB configures a BWP, itincludes parameters: BWP Numerology (u) BWP bandwidth size Frequencylocation (NR-ARFCN), CORESET (Control Resource Set). For Downlink, UE isnot expected to receive PDSCH, PDCCH, CSI-RS, or TRS outside an activebandwidth part. Each DL BWP includes at least one CORESET with UESpecific Search Space (USS) while Primary carrier at least one of theconfigured DL BWPs includes one CORESET with common search space (CSS).For the uplink, UE 110 shall not transmit PUSCH or PUCCH outside anactive bandwidth part. UEs 110 are expected to receive and transmit onlywithin the frequency range configured for the active BWPs with theassociated numerologies. However, there are exceptions; a UE may performRadio Resource Management (RRM) measurement or transmit soundingreference signal (SRS) outside of its active BWP via measurement gap

In an exemplary embodiment, the radio network controller 131 canimplement logic is implemented with computer-executable instructionsstored in a memory, hard drive, or other non-transitory storage ofdevice for execution by a processor contained within. Also, the radionetwork controller 131 can be configured with a remote radio unit (RRU)160 for downlink and uplink channel processing. The RRU 160 can beconfigured to communicate with a baseband unit (BBU) 139 of a basestation controller 131 via a physical communication link and communicatewith a wireless mobile device via an air interface.

In various alternate embodiments, the base station 138 can be separatedinto two parts, the Baseband Unit (BBU) 139 and the Remote Radio Head(RRH) 141, which provides network operators to maintain or increase thenumber of network access points (RRHs) for the node (gNB), whilecentralizing the baseband processing functions at a master base station175. Using a master C-RAN base station 175, the power management system,170, can be instructed to coordinate operations in the tangent of powerlevels of multiple cells (121, 122, and 123).

FIG. 2 is an exemplary flow diagram of a smart bandwidth adaptation callflow of the smart bandwidth (BW) adapter controller in accordance withvarious embodiments. In FIG. 2 , initially at step 5, the smart BWcontrol is enabled or always configured in on-state monitoring for an ACpower outage or light network load. At step 10, detection by the BWadapter controller is made as to whether a change in state is occurringof an AC power outage or light network load. For example, a feedbackcommunication loop for power management of a base station responsive toa commercial power interrupt or failure of the base station powermanagement system in a wireless data networking environment, or a NewRadio AC power outage detection by distribution unit (DU) or centralunit (CU) connected to the 5G network.

The Distributed Unit (DU) or Central Unit (CU) or management function(NFMF) can also detect AC power outage by using the network model ofFault, Configuration, Accounting, Performance, Security (FCAPS) andactivate the appropriate solution. For example, during an AC poweroutage, the RF radio will notify the control unit DU/CU, and the DU/CUunits will to initiate moving of all or nearly all of the user trafficto the designated lower BWP(s) (e.g., initial BWP) while shutting downall or almost all of the other BWP in the current operating carrier.

Next, if there is determined that there is an AC power outage or lightnetwork load at the node, then at step 15, the small BWP(s) will beinitialized. The initial active small BWP(s) are for a UE during theinitial access until the UE is explicitly configured with BWPs during orafter the establishment of the RRC connection. The initial active BWP isthe default BWP unless configured otherwise.

At step 20, move or assigns users to small BWP(s). For example, based onthe network configuration, the DU/CU may move all or nearly all theusers and/or slices to the smaller BWP(s) during the AC power outage orduring the light network load to minimize power consumption. The gNBwill notify the UEs of the change in the assigned BWP. The UEs willcease to monitor the current BWP and will switch to immediatelymonitoring only the lower BWP. In a multi-carrier operation, the DU/CUcan also move all the traffic to a single carrier based on BWP and/orslice prioritization configurations.

The reduction from a wider bandwidth has a direct impact on the peak,and users experience data rates. Operating UEs with smaller BW than theconfigured CBW, reduce power and still can allow support of the widebandoperation. At step 25, the adaptive bandwidth module continues tomonitor for an AC power outage or light network load if the commercialpower is resumed then at step 35, the BWP is restored for the entirechannel. After full power restores or loading on the RAN has increased,gNB can re-activate all the dedicated BWP and/or slices and move theusers seamlessly to their respective BWP and/or slice(s).

At step 40, the normal operation is resumed again, and the powerconsumption levels are raised. Alternately, at step 25, if there isstill determined to be an AC power outage or light network load, then atstep 30, the feedback operation occurs to delay restoring the normaloperation with all the BWPs for the entire channel BW The node is stillplaced in a limited operational state configured with the small BWP(s),and the BW adaptive unit continues to wait for the resumption of thecommercial power or increased loads.

The reduced bandwidth operations and the corresponding assignments tothe UEs can also occur in a Multi-User MIMO (MU-MIMO) operation if a RANScheduler is operating in MU-MIMO operation and decides that all ornearly all of the current serving users can be assigned to the samelower physical resource blocks (PRBs). In this case, the DU/CU units canshut off the current transmission that is occurring on othersub-carriers (i.e., each PRB can consist of up to 12 subcarriers) whichwill also result in power savings of the BS The lower PRBs assignmentsfor MU-MIMO can also be prioritized based on the BWPs active and/or theslicing priorities that have been predefined.

FIG. 3 is an exemplary flow diagram of a smart bandwidth adaptation callflow of the smart bandwidth (BW) adapter controller in accordance withvarious embodiments. In FIG. 3 at step 305, in the smart BW adaptationcall-flow, like in FIG. 2 , the BW adapter controller is initiated, andat step 310 determines whether a change in state is occurring of an ACpower outage or light network load is being operated at the node. If thedetermination is in the affirmative, then at step 315, the initializeslice reassignment process takes place. At step 320, various slices arereassigned to small BWPs from their current slice assignments. Thenetwork slicing is configured that each active slice is tied torespective BWPs which enable during the AC power outage or light networkload the systematic automated transfer of each active slice to a BWP ina scheduled order to reduce the power consumption by the UEs accessingthe gNB by preconfigured slice control and BWP association

For example, an operator can choose to merge all the active slices inthe network or at a node into smaller BWPs. The operator may choose todefine profiles, settings, etc., of each BWP that make up the BW andalso alternative slice mappings for assignment during the powerinterrupt, AC power outage, light network load, etc. this can bebeneficial when there are multiple BWP that can be defined for usage insuch conditions when the full BW is not needed or when power savings aredesired. The offering or selections can be assigned all at once,incrementally, and also can be reassigned to normal operation in alikewise manner. The operator also can simply choose to close some sliceofferings when desired and continue to enable only certain higherpriority slice(s) for access by premium, or both premium and non-premiumused. Further, usage can be selected for an entire preset period orconfigured for a given duration to select user sets. At step 325, the BWcontroller adaptor like in FIG. 2 , continues to check whether thecommercial power has not been restored and, if not, then continues viastep 330 with the configured mapped slices selected for reduced power orload operations. At step 335, once the commercial power is resumed orthe load is increased beyond a certain threshold, all the slices thathave been prior or can be enabled without the prior restrictions will berestored, and normal operations will be restored to all the UE's givenaccess.

FIG. 4 illustrates a functional diagram of mini slot configurationbefore and after an AC power outage of an exemplary smart scheduler formini-slot allocation and adaptation call-flow in accordance with variousexemplary embodiments. In various exemplary embodiments, in FIG. 4 thenetwork 400 in response to an AC power outage or light load at 410 canprovide a desired DL/UL transmission pattern to UL and DL requests fromvarious UEs. In FIG. 4 , in an exemplary embodiment, there is shown anoperating carrier (e.g., 20 MHz) with a default BWP arrangement coupledto a scheduler unit before the AC power outage that schedules data withall the slots enabled for the use of the UE during the initial accessfor the data allocation by gNB (i.e., RAN+DU/CU). If an AC power outageoccurs or there is a light load, and some of the channels are not used,then at 420, the mini-slot algorithm is enabled for enabling anddisabling certain mini-slots in a slot configuration period. Asmentioned, Mini-slot occupies 2, 4, or 7 OFDM symbols in the normal slotconfigurations and can assist in achieving low latency in datatransmission. The PDSCH channel is used to carry DL user data, and the5G channel types cover logical channels and transport channels used inuplink and downlink with a mapping between them. In response to themini-slot scheduling at 420, in the uplink channels at 425, and thedownlink channels 430, the number of mini-slots is reduced. Likewise, inthe downlink channels, the number of mini-slots can also be reduced.That is, the scheduler only enables certain mini-slots. At 435, onceagain, the network determines if the AC power outage or light load iscontinuing. If not, the application reverts back to restore normal slotoperation 450, and the mini-slot not enabled, is enabled, and thechannel for normal slot operation is restored. Reducing the mini-slotnumber reduces the time for the UE to receive a message, and reduces thewait time for transmission (latency receipt and wait times). The UEproportional time in the connected state is reduced after receiving ortransmitting the last packet. After this, UE would transition to an idlestate, hence the power consumption of the UE is reduced (i.e., atradeoff of the connection latency time by the UE).

FIG. 5 illustrates an exemplary diagram of a power management system forchoking off active channels, beam management, and filtering networktraffic by a scheduler and control unit responsive to a power outagedetected in a network in accordance with an embodiment.

In various exemplary embodiments, in FIG. 5 the network 500 in responseto an AC power outage with/without a set of congested channels at 510initiates several actions to conserve power at a cell site. For example,the actions may include at 515, initializing an adaptive channelmanagement solution, at 520 initializing at adaptive beam managementsolution, and at 525 initializing an adaptive network trafficmanagement. Next, the power management actions at 530 include chokingselect congested channels. The power consumption is reduced by cuttingoff heavily loaded channels to a limited number of users. Upon a chokingoff of each channel, a corresponding functional relationship of areduced amount of power is exhibited and detected by a control unit, orthe scheduler, etc., and the choking action of the channels is measuredand determined in accordance with the detected power reductions. Hence,rather than applying traffic management to guarantee fairness onlyamongst users, the traffic management algorithms or solutions will takeinto account additional consideration such as levels of congestion ofnetwork traffic per channel amongst users to reduce power consumptionincrementally at the cell site based on each individual channels chokedor not enable which in turn can extend backup battery life.Additionally, at 540, the beam management manages power consumption of aset of beams across the cell site (i.e., the power management for thesignal to noise ratios) to ensure stable communications of networktraffic but also to arrange power supplied to various MIMO systems moreeffectively taking into account the channel choking actions. The MIMOantennas communicate with multiple clients using focused beams of radiowaves (“beamforming”). This increases channel efficiency along with datatransfer rates and reduces the possibility of interference. The beammanagement to reduce power needs for the downlink and uplinktransmission and reception. Finally, at 545 the network traffic can alsobe filtered to minimize frame congestions and slot usage, thereby savingpower. For example, traffic shaping is implemented that can reduce powerconsumption at a Base Station by traffic shaping rules to allowreal-time voice and video and to block or throttle applications such asP2P, social networks, etc. When channels are not congested, the powerconsumption is reduced because there is a low traffic rate. This trafficshaping is not particularly effective during high traffic loads becausethere is throttling back traffic, and certain application use may stillnot leave empty subframes left to enable a low traffic rate andsubsequent lower power consumption. At 550, once again, the networkdetermines if the AC power outage with/without the congested channeltraffic is continuing. If not, the application reverts back to restorenormal channel and traffic operations 565, and the channels not enabledor choked, are enabled at 560, and any filtered traffic in the trafficshaping steps is no longer subject to such actions.

FIG. 6 illustrates an exemplary flowchart of choking channels, trafficshaping, and beam management by a power management system communicatingwith a scheduler and a control unit to reduce power usage responsive toAC power outages; power interrupts with or without congested channeltraffic.

In FIG. 6 , at task 605, an AC power outage is detected, or it isdetermined in response in a variety of ways, for example via feedback(i.e., messages) communicated and received by the Base Stationcontroller of an impending AC power interrupt or AC power outagedetected in another part of the network, from the monitoring of theinput current to the current Base Station, or from monitoring trafficchannel congestion at various slots and mini-slots in use for UL and DLtransmissions. In addition, channel congestion is detected or notdetected for various channels transmitting data between the cell siteand the user. At task 605, the power management systems are initialized.For example, the adaptive channel management system is initialized inresponse to channel congestion and power outage. At task 610, trafficshaping management is applied to filter or shape network traffictransmission. For example, the scheduler unit supports low latency andreduced power consumption for each reduced traffic transmission byenabling UL and DL transmissions over variable periods of traffic datasub-frames of each mini-slot based on a set of frequencies where atraffic data sub-frame is a fraction of a series of packet datatransmitted in a slot. At task 620, the channels at a cell site areanalyzed for congestion levels. Channels will higher levels ofcongestion are selected in a schema for choking off. At task 630, achannel is choked and a functional relationship is determined for anamount of power that is reduced in the cell site usage as a result ofthe channel disabling or choking off. In addition, the bandwidthallocated for the other channels and the cell site remains unchanged.Also, users can be moved in a schema to other channels from ones thathave been choked off. For example, The clients can be moved from one 20Mhz or 40 Mhz channel to another. At task 640, power levels to the setof beams used for transmission at the cell site are modulated. Forexample, the channels that are cut off can cause less traffic andrequire a lower power level or a change in the operating settings ofcertain beam sets at the cell site. The signal-to-noise ratios can bechanged or the user can be shifted over to different beam frequencies.In addition, by identifying decreases in channel data rates, coordinatedcontrol of the power supplied to particular beams can be adjusted whileat the same time maintaining a certain level of beam efficacy. Hence,dynamically configure setting for power supplied for beam configurationsused for UL and DL transmissions at the cell site to maintain currentlevels of beam signals across the cell site while reducing powerconsumed at cell sites of the network. At task 650, the network powerlevel or outage is again rechecked. If network power is restored, thenat task 660 the normal operation of the channels is restored.Additionally, any traffic shaping actions for reduced power consumptionas well as beam power reductions are also restored to normal operatingconditions. During the power outage, the initial BWP parts remain thesame. That is, the power management system does not change the number ofBWP to reduce power consumption across the cell site but reduces thenumber of channels thereby maintaining at least the same bandwidth ofthe selected channels that are not choked off.

FIG. 7 is an exemplary illustration of a UE and network configuration inaccordance with an embodiment. The UE 710 includes a processor 815 forperforming various logic solution functions for registering andreceiving broadcast system information, initiating PDU sessionsperforming cell selections and reselections, ranking neighboring cells,configuring different modes of operation of the UE, etc. The UE 710 mayinclude a cell reselection module 725, input/output interfaces 705,memory 730 for storing measurement reports, rankings data of neighboringcells, and a measurement module 735 for calculating by various solutionsdistances and other criteria for neighboring cells, etc., and foraccessing cells within the vicinity for the premium and non-premiumusers. The network 740 may include a base station 775, processor 745 forregistering UE for slice access, cell ID modules 755, broadcast module748 for broadcasting slice ID, slice offset values for neighboring cellsand other system information, authentication module 750 forauthenticating a UE, network slices 770, etc. and a BW adaptation module760. The UE 710 communicates with the network and reads broadcastedsystem information at cell 810 in which the UE 810 is camped in an idlemode. For example, if the UE 710 is camped at a cell A, then the UE 710would receive slice IDs and slice offset values for neighboring cells ofcell A via the transceiver 720 and process the information via theprocessor 715 to perform measurements and calculate using cellreselection equations of the cell reselection module 725 (e.g., using acell reselection logic or process) to select a next cell where the cellreselection process is based on a ranking of the neighboring cells.

The scheduling unit 755 can communicate a control unit 757, and a BWadaptation module 760, etc. . . . via element management systems (EMS)790 (i.e., or alternate control units) to direct various logiccomponents in channel management and the control unit 757 in trafficshaping and beam management. In addition, the control unit 757 with thescheduling unit 755 can perform actions for allocating channels,allocating beams, filtering network traffic, allocating slots,mini-slots and setting mini-slot configuration periods across channelsby managing a set of frequency settings by an automated workflow of thecell 810 of the parts (shown in FIG. 1 ) of the radio receiver, the UPS,battery circuit (i.e., DC power supply), the cell site(i.e., node)calls/dropped calls/throughput in operation, the server. The EMS 790monitors via the distribution units (DUs) 830 and the central units(CUs) 840 the various nodes and cells in the network and controls orsend instructions to the various components of the cell 810 to maintainthe quality of service (QoS) of the cell site. The automated workflowmaintains the network availability and monitors the status of networkdevices, including the commercial power supplied to the network. The EMS790 can also be connected to multiple eNodeB for power management. Whenan AC power outage in the network occurs, the automated workflow whichis monitoring the network instructs the EMS 790 via various logiccomponents to reduce the output power of the radio receiver and alsotakes into account other factors by communicating with the radioreceiver, cell site via a router (or another communication link)connected to the server 820 in reducing the output power fortransmission. This, in turn, reduces the DC power and the draw on theUPS.

In an exemplary embodiment, the server 820 can be configured as NB-IoTServer is a software for data collection and monitoring andcommunicating via the router for activating the automated workflow viathe EMS 790 and can display the log messages of each base station andthe survival status of all sessions (including information such assignal, power, etc.).

After the detection of an interrupt of the commercial power, powerfailure, power loss, and/or AC power outage of the network, theautomated workflow, which is monitoring the components and the network,detects the change and the power loss. The automated workflow inresponse to the detected power loss implements the configurationmanagement functions via the scheduling unit 755 for mini-slotallocations and frequency settings, the BW adaptation module 760 ofslice assignments, and available BWPs at the cell 810. The EMS 890communicates with the radio receiver, the server 820, and othercomponents associated with the cell site, to send messages via the cellsite router to receiver collect cell statistics, and to executeappropriate plug and play functionality of the base station radioreceiver. The automated workflow executes various functions to theelement management system based on decisions from the BW adaptationmodule 760 and data from the cell site and base station.
